Bie it knownithat I, Entree, a citizen of theUnitediStates,residing at the city of Worcester, inmthe county of Worces-V 6 terand State of Massachusetts, have invent? ed new and useful Improvements in Toy Hand Grenades, .of-whieh the following is a specification. A i i This invention relates to improvements in toys and more particularly to hand grenade toys. 7 7

One of the objects oi my invention isto provide a simple, inexpensive and highly efficient toy closely resembling in ap.pear-' ance andeiilectfthe deadly hand grenade-used in the recent war.

Another object of my invention is to pro vide a novelty in the nature of a rubber hand grenade designed to be-used over and over again without the use of any explosive and yet capable when throwntromthe hand of emittinga sharp, quick report as any torpedo does.

still further object of my invention is to providea devicemade of two rubber seg ments; ofsimila'r design and construction having a cylinderand piston connection and so operable that when brought together the pistonis set so as to make a report by sue. the two segments forcibly fly apart.

With the abov'eand other objects in view my invention consists in the arrangement, combination and details 1 of 'construeti on dis 36 closed in the drawings and then more particularly pointed out in the appended claims, I

In the drawings which are merely illustrative of my invention -1 and 1 designate a pair of sim'ilarly sized and shaped rubber segments shaped externally so as to simulate the hand grenades used in the World "War, each segment being cup-shapedin configuration. The segments are made preferably of rubber orsimilar material. Segment 1 teminates at one end in a tapering nipple 2 formed with an axial port-3 widened as at 4 to provide a seat for a suitable check valve 7 the valve seat being covered by a piece- 6 having an outlet passage 5 for'the vein-t port 3. Communicating axiallywith port 3 is a relatively wider and elongated piston chamber 8 formed in an air cylinder 9 which'projects centrally and axially within segment 1 and is formed with an annular flange 11 arranged concentrically around cylinder 9 so as to provide an annular groove 10 forming ais'uitable spring seat.

Segment 1 is formedinternally' thereofwith an axial central boss 12 having a central bore 13 forthe reception of the stub 20 of a preferably wooden piston 243 formed; between its ends with the cylindrical enlargement 22 having the shoulder 21 which.

seats uponjthe 'outer flat face of boss12. The enlargement 22 is formed with an annular spring seat 23 substantially ofj'even diameter withthe annularfllange l1. :Ttwill be'seen that the piston rod 24 pr'oiectssnug- 1y intothe air cylinder-passage "8 and that the piston head 27' is Secured. to "the piston rod 24 by a screw 26 threaded in the threaded hole 2 5 formed in thejpiston rod,

fits snugly at opposite ends "thejanhular IOU ill

seats provided therefor 11 and 23 and is thus properly positioned and made of a length to normally separate the annular bead 36 011 segment 1 from the annular groove 37 formed in segment 1 as clearly shown in Figure 6. The segments are shown in Figure 6 just as they should appear before cooking or priming the toy hand grenade, it being seen that the spring is uncompressed and fits the spring seats aforementioned, this spring being fixedly secured in the annular groove 10 and portion 22 but is unattached in seat 11 so as to allow the segments 1 and 1 to separate and fly apart in simulation to the flying fragments of a real hand grenade when the latter bursts. A string 16 is adapted to con nect segments 1 and 1 so they will not become separately lost, the ends of this string being fastened to the lugs 15 and 16. Segment 1 is formed with the axially disposed openings 19 while segment 1 is similarly formed with the openings 18. A pair of straight stout wires 31 and 32 are provided which project thru the openings 18 and 19 being formed at one end with the hooks 33 firmly secured into segment 1, the free terminals of wires or rods 31 and 32 being formed withslight hooks 35. It should be noticed (see Figure 1) that the holes 18 are considerably wider than the diameter of rods 31 and 32 so that the hooks 35 cannot obtain a hold therein, so in order to connect the latch rods to make them contribute to hold segments 1 and 1 into contact the releasable trigger in the shape of a V-shaped piece is provided. Note that rods 31 and 2 (see Figure 6) are made just long enough to equal the effective length of the completed grenade after the segments 1 and 1 shall have been pressed together. Formed terminally on the V-shaped trigger arms 39 and 40 are knobs 12 which engage the hooks 35 of the latch rods. after segments 1 and 1 have been primed by being pressed together from the position shown in Figure 6 to the position shown in Figure 1, this act tend ing to compress the coil spring 28 and inducing the piston head 27 to move towards the inner end of the air cylinder 9 and in doing so unseating check valve 7 so air may be forced out thru vent 3 and port 5, and when this takes place bead 36 will fit snugly in groove 37 and the trigger holds the latch rods so they cannot become released and thus the spring is set. The string 38 is secured at 40 to the trigger.

To intonate the toy grenade with the parts as shown 111 Figure 1 the string 38 is taken hold of in onehand and the grenade is thrown violently, thereupon the trigger is released. the spring quickly relaxes and pulls the piston head 7 sharply in air chamber. so this head by suction closes valve 7 in its seat and when piston. head has left air cylinder the sudden report of a cartridge will be heard. Thereupon the parts of the top hand grenade are as shown in Figure 6 and are ready to be put together again and operated in the manner already explained.

Numerous modifications may be resorted to in practice Without departing in principle from the details of construction herein disclosed.
